Mouse Functions Over Axes on Top of Each Other

I have a GUI in AppDesigner in which I have 2 axes objects on top of each other (i.e.: their position property is the same). I am plotting a curve on the "bottom" axes and I use the "top" axis only for formatting purposes, such as having additional X and Y rulers on the graph with different scaling, colors, units, etc.

Is there a way to keep the usual mouse functions working, such as drag-to-pan, scroll-to-zoom and marking points on the curve by clicking? These functions no longer work properly because they act only on the axis on top, which is the one where there are no curves effectively being plotted.

Set PickableParts 'none' for the top axes
